JOSEPH TITCHETT, OF WARRINGTON, ENGLAND.

GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 643,755, dated February 20, 1900.

Applicationfiled January 23,1899. Serial No. 703,138. (No model.)

To aZZ whom it may concern;

Be it known that I, JOSEPH TITCHETT, a subject of the Queen of Great Britain, residing at lVarrington, in the county of Lancaster, England, have invented certain new and useful Improvements in Gas-Stoves, of which the following is a specification.

This invention relates to improvements in the arrangement and construction of gasstoves for cooking purposes, and is designed for the purpose of heating the oven with the least expenditure or loss of heat.

The invention will be fully described with reference to the accompanying drawings.

Figure 1 is a front sectional elevation of the stove. Fig. 2 is a side sectional elevation. Fig. 3 is a plan with the top plate removed, showing the top of the oven. Fig. 4c is a plan from below with the bottom plate removed, showing the bottom of the oven.

The stove is constructed with an interior chamber or oven A, into which no waste or unconsumed gas can enter. The oven A is surrounded on all sideswith a number of passages or fines-through which the heated gases or other products of combustion are conducted or caused to circulate, so as to pass in succession over the bottom, top, and sides of the oven. The oven can be made in one casting or in sections, as required, and can also be made of sheet-iron.

Beneath the bottom CL of the oven A is constructed a combustion-chamber B with a bottom plate 0, provided with a slot 0, through which the gas jets or flame from a burner D pass and impinge upon the bottom a of the oven near the front. The combustion-chamber extends to the back of the oven and at the sides is inclosed by the two side plates 19. At the back of the oven is a vertical flue or passage E, extending the full width and height of the oven and opening into a horizontal flue or passage F, constructed over the top of the oven A.

At both sides of the oven A are constructed a number of vertical fines or passages G G G G and H H H H The fiues or passages G G G G are formed by a number of vertical ribs 9 g g g and h h 71, h These ribs are cast on the inner side of the external casing K and fit into ribs or grooves a a a a cast upon the external side of the walls of the oven A, a tight joint being formed by means of asbestos or other non-combustible packing. The bottom of the vertical side fines or passages is formed by a horizontal rib L. The vertical ribs g g h b have a passage beneath them, and the vertical ribs 9 g h it have a passage above them to cause the heated gases to pass up and down in zigzag fashion in contact with the sides. The passages and fines are inclosed by an outer casing K, formed of two plates 70', with a space between them packed with a non-conducting packing K, such as slag-wool or asbestos, to prevent radiation of heat.

An outlet or exhaust aperture P is formed near the top of the back plate and is fitted with a damper R to close it, the damper being operated or controlled by a rod or handle 0'.

An aperturep is also made in the oven top,

opened and closed by a damperp. The damper 19 is also operated by the rod 0. The aperture p is formed in the top of the oven A, through which the heated gases can be permitted to enter the oven to heat it or dry it or to allow the escape of steam. This aperture is closed by a damper or shutter 29'.

A lower chamber A, with shelves (1?, may be formed below the burner D to heat or maintain the heat of articles placed therein.

Boiling, grilling, or other burners D may be placed above the top plate of the stove with a suitable frame S. The frame S is mounted upon four legs 3, one at each cornor, a space being thus formed around the grilling or roasting space, which allows of easy access thereto at any side of the stove.

The grilling-burner D is made with two longitudinal tubes, with apertures 01.

In operation the heated gases from the flame of the burner D pass through the combustion-chamber B, along the under side of the oven A, up the back flue E, along the horizontal flue F, in contact with the top of the oven, and down through the front corner flues GH, and up and down through the dues G G G and H H H in zigzag fashion against the sides of the oven.

What I claim as my invention, and desire to protect by Letters Patent, is

A gas-stove comprising in its construction the oven A the combustion-chamber B the bottom plate 0 provided with a slot 0 inclosing the combustion-chamber, the burner D the vertical flue E at the back of the oven the horizontal flue F on top of the oven the side fiues G G G2 G3 and H H H H the vertical ribs 9 g g g and h h k h inclosing the vertical sides lines the outer casing K comprising the plates 7; 7c and the non-conducting packing K substantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing I0 witnesses.

JOSEPH TITCHETT.
